Mobile One charger will charge everything? Here is the Green Cell USB-C 60W PD test

A smartphone, a tablet, a laptop, a portable gaming console, a smart watch, a camera and much more … each of them with its own charger, which means that each of us has at least several of them at home. It does not have to be that way!

It is true that the first attempts to standardize the charging standard were made already in 2009, which would end our problem of juggling with chargers, and most importantly, littering the environment, because then 14 major manufacturers, including Apple, Samsung, Nokia or Huawei, decided to sign an appropriate memorandum , in which they undertook to unify chargers (use of micro-USB port) from 2011, but this plan never came into force. Hence the next interventions of the European Union, which takes this problem seriously and intends to end up with the arbitrary producers – until recently it was limited only to voluntary cooperation, but for some time the law that compels companies to standardize mobile phone chargers is also at stake.

And although some producers actually kept the provisions of the said system, however, Apple remained with the authoring technology Lightning, and some time ago we got another “problem”, namely a new USB port type C. And although in practice it is the best, what about charging devices have met us in recent years, it introduces even more confusion, as well as various fast charging technologies with different energy requirements. Does this mean that we are actually doomed to having at least several chargers at home, which are difficult to find every time when they are needed most? And further littering the environment, because, as the estimates from a few years ago say, every year in the European Union is produced 51 tons of electronic waste coming from incompatible chargers?

Fortunately, no, but on condition that we will be conscious consumers. Because although we will not jump over certain things and the producers will continue to load the charger for each new equipment, we can always put it in circulation so that others do not have to exchange the broken ones for new ones, and limit themselves to one at home. What’s more, when buying new devices, pay attention to the connectors and charging standards used in them to strive to unify your home collection. In this way, we not only protect our environment, but also significantly simplify our lives, especially by choosing such proven solutions as USB-C with the Power Delivery standard. A good example is the Green Cell USB-C 60W PD model, which went to our editorial office at the time when obedience refused to us an original power supply for the Xiaomi Mi Notebook Pro laptop.

As it turned out, although Xiaomi devices are in official sale in our country, this particular model is not – our copy was imported straight from China, so buying the original charger is not so easy. Of course, we could again buy on Chinese sites, but as you know, you have to wait long enough for delivery, and popular auction sites only offered expensive replacements from unknown producers that did not inspire our confidence (there is no lack of chilling history in the web suspicious chargers in the main role). That’s when it turned out that the right power supply has the Polish Green Cell brand in its offer, and what’s more, we can also use it to charge other devices, like tablet, smartphone, navigation, camera, sports watch and Nintendo Switch portable console, without any risk for these appliances. And already here we can tell you that it has replaced all our other chargers, often beating the possibilities of original power supplies. This is largely due to the Power Delivery 3.0 standard mentioned earlier and supported by Green Cell USB-C 60W PD, which is an optional extension for USB-C, introducing configurable voltage and current, which is an attempt to unify quickly fast charging standards.

Let’s start from the beginning, Green Cell USB-C 60W PD comes to us in a small cardboard box in typical colors of this brand, i.e. green and black, with a dust jacket containing device graphics and basic specification. In the middle there is a charger and a 2 meter cable, which is not so obvious from the competition, but the manufacturer probably wanted to ensure the quality of this element. The power supply cube is small, because it measures only 6.4 x 6.4 x 2.7 mm (plus plug) and weighs 146 grams, so we can easily take it with you everywhere. For this was made very carefully, with a matte black plastic with a glossy accent and GC logo, so it looks elegant – in our case, much better than the original white charger from the Xiaomi laptop, which very quickly began to show signs of wear, and in any way it did not correspond with the steel color of the laptop. The cord is long and thick enough, and at the same time flexible enough, which guarantees that it will serve us for a long time.

As for the technician, as the name suggests, the charger has 60W of power, but thanks to voltage and current regulation it can be used to charge devices: 5V-3A, 9V-3A, 12V-3A, 15V-3A and 20V-3A. This means it is equally well suited for charging small devices like smartphones and those much more demanding, like laptops. We tested it with many different devices, including smartphone, tablet, smartwatch, Nintendo Switch or laptop, but more accurately we will present the charging of the two most used ones, namely the Motorola Moto X4 and the Xiaomi Mi Notebook Pro. It is worth noting, however, that the Green Cell USB-C 60W PD charger worked great with every device that we used to charge it and in all cases achieved results at least as good as the original chargers, and very often even better. What’s more, neither the device nor the charger warmed up more than usual, and the highest temperature of the power supply we noted was 34.4 ℃, so we are talking about plastic at most warm to the touch. In this context, it should also be mentioned that the charger can boast a number of protections, such as temperature control or protection against short circuits and overvoltages.

Returning, however, to the very charging of the Xiaomi Mi Notebook Pro (8000 mAh) and Motorola Moto X4 (3000 mAh), the measurement with a wattmeter shows that in the first case we are talking about charging with full declared power, or even a slightly higher, around 61W, and in the second with 10W power. Unfortunately, the smartphone supports fast charging of Quick Charge 3.0, and only version 4.0 is compatible with Power Delivery, so we can not count on using the full potential of the device, but the Green Cell charger loads them faster than others without any quick charging. However, if we take the newer smartphones, which can already be proud of Quick Charge 4.0, as rented by us for a moment to test Xiaomi Mi 9, it turns out that the charger from Green Cell is doing great and the charging time of the smartphone is less than an hour. For those who are interested, there is also a short information that when the charger is idle, the meter shows a result of 0.9W. This is how the loading times for the devices mentioned look at 0%:

Motorola Moto X4

30 min – 35%

60 min – 73%

90 min – 92%

118 min – 100%

Xiaomi Mi Notebook Pro

30 min – 34%

60 min – 71%

90 min – 85%

127 min – 100%

All in all, Green Cell USB-C 60W PD is a great choice for anyone looking for a high-speed universal charger for multiple devices with a USB C-type connector that has enough power to recharge even more demanding equipment, such as laptops. The product that came to our editorial office not only fulfills its task well, but also looks elegant, which allows us to use it freely during business meetings, for example. There are also no concerns about user safety, as in the case of replacements from unknown manufacturers, because the manufacturer took care of numerous security features, including temperature control or protection against short circuits and overvoltages. Particular attention to this Green Cell proposition should also be given to users of Apple laptops who need a new charger, because the price of PLN 129 is nothing compared to what the American giant wants for similar solutions. In short, we recommend it!
